Why, you have already shown you refuse to accept them.
“In 1911,
Paul Langevin gave a "striking example" by describing the story of a traveler making a trip at a
Lorentz factor of γ = 100 (99.995% the speed of light). The traveler remains in a projectile for one year of his time, and then reverses direction. Upon return, the traveler will find that he has aged two years, while 200 years have passed on Earth.”
But remember, the traveler only travels at a constant speed, not a continuing acceleration.
“In
physics, the
kinetic energy of an object is the
energy that it possesses due to its
motion.
[1] It is defined as the
work needed to accelerate a body of a given mass from rest to its stated
velocity. Having gained this energy during its
acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.”
So unlike the traveler example, the earth is continuing to gain kinetic energy, it is not simply being maintained until reaching its stated velocity. The velocity has not yet been reached, since acceleration is continuing to increase, and is currently by some z values .99 the speed of c.
So assuming your calculations of 4 billion years, just for one that has attained the stated velocity and keeps the same kinetic energy the entire trip, only 20,000,000 years will have passed for the traveler. But the same amount of kinetic energy is not being maintained the entire trip, instead it is continuing to increase. Therefore the calculations must be done exponentially.
This reduces that 20,000,000 years down in the range of 20,000.
But even without the proper exponential corrections, we are down to 20 million years, far too short a time for the processes people claim to have occurred in 4 billion years.
This continued gain in kinetic energy is also why life has reduced in size dramatically, energy equals mass, mass equals gravity. So not only do clocks speed up and decay rates the further back one goes, but mass decreases and gravity also decreases, allowing larger life to flourish in the past that would not be able to stand up to the forces of gravity we see today. So you see, proper application of Relativity not only solves the problem of how dinosaurs could grow so large under today’s gravity (because it wasn’t the same strength as today), but also corrects for incorrect age calculations.
